Question

10. A rectangle has width the same as a side of a square whose perimeter is 20 m. the length

of the rectangle is 9 m. Find the perimeter of this rectangle.

Answer 1

The perimeter of the rectangle is 28m

Explanation:

Perimeter of a square = 4 x side length

20 = 4 x side length

side length = 20/4 = 5m

width of rectangle = 5m

length of rectangle = 9m

Perimeter of rectangle = 2(l + w)

= 2(9 + 5)

= 2(14)

= 28m
