Answer:
a. 70 square centimeters
Step-by-step explanation:
The area of the composite figure = Area of trapezoid + Area of rectangle
Area of trapezoid = [tex]\frac{1}{2}[/tex] (a + b) h
= [tex]\frac{1}{2}[/tex] (12 + 13) × 5
= [tex]\frac{1}{2}[/tex] ×125
= 62.5
Area of trapezoid is 62.5[tex]cm^{2}[/tex]
Area of rectangle = length ×breadth
= 5 × 2
= 10 [tex]cm^{2}[/tex]
Area of rectangle is 10[tex]cm^{2}[/tex]
The area of the composite figure = 62.5 + 10
= 72.5[tex]cm^{2}[/tex]
To 1 significant figure, the area of the composite is 70[tex]cm^{2}[/tex].
Answer:
Step-by-step explanation:
it's really b. Just did the test and put 70 and got it wrong.
