Answer:
D. This is a right triangle because 36^2 + 15^2 = 39^2
1521 = 1521
Answer: 100 cm2
Step-by-step explanation:
Hi, to answer this question we have to decompose the figure in to a triangle and a rectangle (see attachment)
Area of a rectangle: base x height
A (R)= 14 x 5 = 70 cm2
Area of a triangle: 1/2 x base x height
Analyzing the figure, the base of the triangle is equal to 14-2 =12 cm.
A (T) =1/2 x 12 x 5 = 30 cm2
Adding both areas: 70+30 = 100 cm2
