Answer:
Perimeter: 74 cm
Area: 300 cm^2
Explanation:
To find perimeter length x 2 + height x 2
Length = 20
Height = 17
(20 x 2) + (17 x 2)
40 + 34 = 74 cm
To find area
Multiply the height by the length
17 isn't the height because you don't measure anything slanted
Height = 15
Length = 20
20(15)= 300 cm^2
