Answer:
Height h = 9 cm
Step-by-step explanation:
Given:
Surface area of cuboid = 102 cm²
Length l = 2 cm
Breadth b = 3 cm
Find:
Height h
Computation:
Surface area of cuboid = 2[lb + bh + hl]
102 = 2[(2)(3) + (3)(h) + (h)(2)]
51 = 6 + 3h + 2h
45 = 5h
Height h = 9 cm
Yes it is a Trapezoid. First, find Perimeter (P), since it's easiest. P = sum of all 4 sides, so:
P = 9.8 + 3.5 + 6.53 + 6.33 = 26.16 yds
Lastly, we need the Area (A) of a trap., which is the average of the parallel bases (usually top and bottom) multiplied by height (h). In our case a1 & a2, and average means add them then divide by 2, so our formula becomes:
A = [(a1+a2)/2]×h
A = [(9.8+3.5)/2]×5.6
A = 37.24 sq.yds.
Answer:
85%
Step-by-step explanation:
34/40 = 0.85
0.85 * 100 = 85
