Question

Work out the area of a rectangle with base, b = 16mm and perimeter, P = 50mm.

Answer 1

Answer: 144mm

Step-by-step explanation: The formula for perimeter is b+b+h+h therefore if you add 16+16 you get 32 then you subtract 50 by 32 leading to 18 then you divide this 18 by 2 which gives you 9. The formula for area is b times h so your equation is 16x9 which is equal to 144.

Answer 2

144mm^2

Explanation:

16•2= 32

50-32= 18

18/2=9

9•16=144
