Answer:
I'm going to use the Pythagoras theorem
1. hypotenus²= base²+height²
h²=80²+18²
h²=6400+324
√h²=√6724
hypotenuse= 82
2. 53²=45²+h²
2809=2025+h²
2809-2025=h²
784=h²
√784=√h²
h=28
3. 40²=b²+24²
1600=b²+576
1600-576=b²
√1024=√b²
b= 32
<em>C) 52 m²</em>
- Step-by-step explanation:
<em>A = 2(lw + lh + wh)</em>
<em>l = 4m</em>
<em>w = 3m</em>
<em>h = 2m</em>
<em>A = 2(4m×3m + 4m×2m + 3m×2m)</em>
<em>= 2(12m² + 8m² + 6m²)</em>
<em>= 2×26m²</em>
<em>= 52m²</em>
