Question

Work out the area of a rectangle with base, b= 26mm and perimeter, P= 74mm

Answer 1

Answer:

b =26

p=74

2(l+b)=74

l+b=37

l=11

A=l*b

=26*11

=286

Answer 2

Answer:

The area is 286mm²

Step-by-step explanation:

Given,

Base as length=26mm

Perimeter P=74mm

Area A=required

From,

P=2(L+W)

74=2(26+W)

74=52+2W we make W the subject

2W=74-52

2W=22

2W/2=22/2

W=11mm

Again from,

Area=L×W

A=26×11

A=286mm²
