We can divide the figure in 3 .
Find the area of each figure and then add the areas:
Rectangle 1:
Length = 10
Width = 5
Area of a rectangel = LEnght x width = 10x5= 50 in2
Rectangle 2:
Lenght :7 in
width= 4 in
Area 2 = 7 x4 = 28 in2
Triangle:
Base = 3
Height = 4
Area of a triangle: 1/2 x base x height
Area 3 = 1/2 x 3x4 = 6 in2
Total area: area 1 + area 2 +area 3 = 50+28+6 = 84 in2
For the perimeter add all the sides:
We are only missing the hypotenuse of the triangle:
c2 = a2+b2
c = √ (3^2+4^2) = 5
Perimeter: 5+7+6+5+10+15 = 48 inches
