Studdy Solution

STEP 1

Assumptions1. The area of the parallelogram is equivalent to 110\frac{1}{10} of the area of a square with side 60 cm60 \mathrm{~cm}. . The height of the parallelogram is equal to 14\frac{1}{4} of the side of the square.

STEP 2

First, we need to calculate the area of the square. The area of a square is given by the formulaAreasquare=side2Area_{square} = side^2

STEP 3

Now, plug in the given value for the side of the square to calculate the area.
Areasquare=60 cm2Area_{square} =60 \mathrm{~cm}^2

STEP 4

Calculate the area of the square.
Areasquare=60 cm×60 cm=3600 cm2Area_{square} =60 \mathrm{~cm} \times60 \mathrm{~cm} =3600 \mathrm{~cm}^2

STEP 5

Now that we have the area of the square, we can find the area of the parallelogram which is 110\frac{1}{10} of the area of the square.
Areaparallelogram=110×AreasquareArea_{parallelogram} = \frac{1}{10} \times Area_{square}

STEP 6

Plug in the value for the area of the square to calculate the area of the parallelogram.
Areaparallelogram=110×3600 cm2Area_{parallelogram} = \frac{1}{10} \times3600 \mathrm{~cm}^2

STEP 7

Calculate the area of the parallelogram.
Areaparallelogram=110×3600 cm2=360 cm2Area_{parallelogram} = \frac{1}{10} \times3600 \mathrm{~cm}^2 =360 \mathrm{~cm}^2

STEP 8

The area of a parallelogram is given by the formulaAreaparallelogram=base×heightArea_{parallelogram} = base \times heightWe know the area and the height (which is 14\frac{1}{4} of the side of the square), so we can solve for the base.
base=Areaparallelogramheightbase = \frac{Area_{parallelogram}}{height}

STEP 9

Plug in the values for the area of the parallelogram and the height to calculate the base.
base=360 cm24×60 cmbase = \frac{360 \mathrm{~cm}^2}{\frac{}{4} \times60 \mathrm{~cm}}

STEP 10

Calculate the base of the parallelogram.
base=360 cm215 cm=24 cmbase = \frac{360 \mathrm{~cm}^2}{15 \mathrm{~cm}} =24 \mathrm{~cm}The base of the parallelogram is 24 cm24 \mathrm{~cm}.
