Question

The sides of a rectangle are in a ratio of 7 : 4. If the perimeter of the rectangle is 176 ft, what is the area of the rectangle? The area of the rectangle is

Answer 1

1792

Explanation:

The sides of the rectangle is 7 and 4

7x, 4x

2(7x+4x) = 176

14x + 8x= 176

22x= 176

Divide both sides by the coefficient if x which is 22

x= 176/22

x= 8

7x

= 7(8)

= 56

4x

= 4(8)

= 32

Area of the rectangle

= 56×32

= 1792
