Answer:
[tex]34 \times 2 = 68 \\ 82 - 68 = 14 \\ width = 14 \div 2 = 7 \\ area = 34 \times 7 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 238 {mm}^{2} [/tex]
Given:
To find out :
The area of a rectangle?
Formula used:
Solution:
we know that,
Perimeter of rectangle = 2(l+b)
82= 2(l+34)
82=2l+68
2l=82-68
2l=14
l=7
Area of rectangle = length × breadth
= 7 × 34
= 238 mm²
