Question

A rectangle is three times as long as it’s wired the perimeter 60 cm find the dimensions of the rectangle a round to the nearest 10th if necessary

Answer 1

width: 7.5

length: 22.5

Explanation:

width: x

length: 3x

Perimeter = 2L + 2W

60 = 2(3x) + 2x

60 = 6x + 2x

60 = 8x

x = 7.5

width: x = 7.5

length: 3x = 3(7.5) = 22.5
