Question

Work out the area of a rectangle with base, b = 34mm and perimeter, P = 86mm.​

Answer 1

Answer: (I am assuming this is 2D?)

Two bases together: 34 * 2

68

Two lengths together is p - two bases:

18

Individual length:

9

Area is base times length

9 * 34

306mm

Answer 2

306mm²

Explanation:

the height h = 86/2 -34 = 43-34=9mm

the area = 34×9= 306mm²
