Answer:
523.1m²
Step-by-step explanation:
Triangle: 1/2bh=1/2(4)(10)=20x2=40 each
Bottom Rectangle: 15x8=120
Side Rectangles: Since the side is a hypotenuse of a right triangle, it’s the square root of 10²+4²=√116=10.77. 10.77x15=161.55
So the total surface area would be 40+40+120+161.55+161.55=523.1m²
23
you add 10m(h) plus 8m(w) plus 15m(l)
