Answer 2

✴️✴️ Given:

perimeter = 169

length = 12cm

breadth = x

✴️✴️To find :

breadth nd Area.

✴️✴️Solution:

perimeter of rectangle = 2(l+b)

169 = 2(12+x)

169 = 24+2x

2x = 169-24

2x = 145 cm

x = 145/2 = 72.5cm

so, breadth of rectangle = 72.5cm

now,

we have to find area of rectangle =>

Area of rectangle = L×B

= 12×72.5

= 870cm²

hence, the Area of rectangle => 870cm².
