Question

A sheet of paper measures 30 cm by 20 CM AC 4 cm wide is cut from it all around find the area of the remaining sheet and also the area of the step cut out​

Answer 1

Step by step explanation :

length of the remaining sheet = 30–4–4 =22

similarly breadth = 20–4–4 = 12

so area = 22×12=264

and area of strip = 30×20 – 22×12 = 336
