What is the area of the composite figure?

A trapezoid has base lengths of 12 centimeters and 13 centimeters. The other sides have lengths of 5 centimeters and 10 centimeters. A rectangle with side lengths of 2 centimeters and 5 centimeters is connected to the side with length 10 centimeters.

a.
70 square centimeters

b.
100 square centimeters

Selected:c.
105 square centimeters

This answer is incorrect.
d.
130 square centimeters

a. 70 square centimeters

Step-by-step explanation:

The area of the composite figure = Area of trapezoid + Area of rectangle

 Area of trapezoid = (a + b) h

                              = (12 + 13) × 5

                              = ×125

                              = 62.5

Area of trapezoid is 62.5

Area of rectangle = length ×breadth

                             = 5 × 2

                             = 10

Area of rectangle is 10

The area of the composite figure = 62.5 + 10

                                                       = 72.5

To 1 significant figure, the area of the composite is 70.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)
