Question

find the length of rectangle whose perimeter is 360 cm and breadth is 80 CM
done in roughnotebook​

Answer 1

Answer:

Perimeter of rectangle= 2l+2b

360= 2l+2(80)

360=2l+160

360-160=2l

200=2l

l=200/2

l=100cm

verification

perimeter of rectangle =2l+2b

360 =2(100)+2(80)

360 =200+160

360=360

LHS=RHS

L= length

B= breadth
