Work out the area of a rectangle with base,

b

= 26mm and perimeter,

P

= 74mm.

Area of the rectangle = 286 mm^2

Step-by-step explanation:

Mathematically, area of rectangle = height * base

We only have the base, and not the length here so we need to get the length first.

Mathematically, from the perimeter

P = 2 (l + b)

74 = 2 (26 + l)

74 = 52 + 2l

2l = 74-52

2l = 22

l = 22/2 = 11 mm

Thus the area = 11mm * 26mm = 286 mm^2
