Answer 2

solution ⤵️

length of the rectangle =10cm

breadth of the rectangle =8cm

area of the rectangle =l×b

area of the rectangle =10×8=80cm²

perimeter of the rectangle =2(l+b)

perimeter of the rectangle =2(10+8)=2×18=36cm

perimeter of a rectangle =2(l+b)

area of a rectangle=l×b

area of a square =a² or l²
