What is the area of this shape?

82cm^2

Step-by-step explanation:

Area of shape=area of big rectangle + area of small rectangle

Length of big rectangle=10

Width of big rectangle=7

area=length x width

area of big rectangle=10x7

area of big rectangle=70

Length of small rectangle=4

Width of small rectangle=10-7=3

Area=length x width

area of small rectangle=4x3

area of small rectangle=12

Area of shape=70+12

Area of shape=82cm^2

ok then what happened.
