Question

(a) The area of a rectangular field is 4823 m².If the length of the field is 91 m, what is its width?Width of the field: 3 m(b) The perimeter of a rectangular painting is 360 cm.If the width of the painting is 84 cm, what is its length?Length of the painting: 1 cm

Answer 1

Part a) Area A = base x width

.Then

width = Area / base

. = 4823 / 91

. = 53

Then answer is

Width = 53 meters

Part b) Perimeter P = 2• width + 2• length

.Then length L = ( P - 2• width)/ 2

. L = ( 360 - 2•84) /2

. L = 192/2 = 96

.

Then answer is

Length L = 96 centimeters
