Question

(a)The area of a rectangular field is 8811m2 .

If the length of the field is 99m, what is its width?
Width of the field: m
(b)The perimeter of a rectangular painting is 360cm.
If the width of the painting is 83cm, what is its length?
Length of the painting: cm

Answer 1

a) 89m b)97

Explanation:

a) You take the area of 8811m2 and divide it by your length 99 to give the width 89 because length x width = area. To check if it's correct you do 89x99 and you should get 8811

b) A rectangular painting has 4 sides, 2 length sides and 2 width sides so you do the width 83 x 2 (because there is 2) = 166 and then 360 - 166 = 194 but to get the length of only one side you do 194 ÷ 2 = 97
