Question

You are designing a rectangular flower Bed that spans across the front of a business and will cover an area of one 25 ft.² if the width is 1/5 the link find the dimensions of the flower bed

Answer 1

Length=11.18 ft

Width=2.236 ft

Explanation:

Step 1

Express the dimensions of the rectangular flower Bed as shown;

length=x

width=1/5 of the length=1/5×x=(1/5)x

Step 2

Express the formula for calculating area;

A=L×W

where;

L=length of the flower bed

W=width of the flower bed

In our case;

A=25 ft²

L=x

W=1/5x

replacing;

(1/5x)×x=25

(1/5) x²=25

x²=25×5=125

√x²=√125 ft²

x=11.18 ft

Length=11.18 ft

Width=(1/5)×11.18=2.236 ft
