Question

the area of a rectangle is 1260 cm² its lenght is 35 cm find its perimeter​

Answer 1

Answer:

142

Step-by-step explanation:

Area of rectangle l×b

1260 = 35×b

b = 1260/ 35

b = 35.

Perimeter of rectangle =2 (l+b)

" " " " " " " = 2( 35 + 36)

= 2 × 71

= 142 cm

Answer 2

Step-by-step explanation:

a=1260cm

l =35cm

b= let be x

so

a=1260

l*b=1260

35*x=1260

x=1260/65=36

so x=36cm

now perimeter of the rectangle

=2(l+b)

=2(35+36)

=2(71)

=142cm
