Area of a rectangle = l x bso, 7x3=21 area=21 perimeter of a rectangle = 2(l+b) 2(7+3) = 2x10 =20 this is your answer by kitty kat amrita
A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.
room is in cuboid shape, so by calculating length(L),breadth(B),height(H) we can find area by formula AREA=L*B*H
An L is two rectangles. Just make sure you only count the place where they intersect once.
