Answer:
d is the answer ly/3fcEdSx link for answer
90
Step-by-step explanation:
When you have Triangles, you have to divide your answer by two. So first, Multiply 3 x 5, which is 15. But you need to divide by two, so 15 ÷ 2 is 7.5. Then, Multiply 7.5 x 12, and now you have 90. Hope this helps!
Equation
A = (b1 + b2)*h /2
Givens
b1 = 5 feet
b2 = 7 feet
h = 3 feet
Sub and solve
Area = (5 + 7)*3/2
Area = 12*3/2
Area = 36/2
Area = 18 Square feet.
OPTION C is the correct answer.
The question isn't completely clear, but I believe that the answer would be 7m. That is the correct format.
