Question

find the length and area of a rectangle whose breadth and area is p=60cm and a=12 cm​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)  

ATQ  

2(l + b) = 60  

2(l + 12) = 60  

2l + 24 = 60  

2l = 60 - 24  

2l = 36  

l = 18 cm  

area = l x b  

area = 12 x 18  

= 216 cm²
