Answer:
Surface area = 144 mi.²
Step-by-step explanation:
Surface area of the triangular prism = bh + (P)L
Where,
b = base of triangular base = 6 mi.
h = height of triangular base = 8 mi.
P = Perimeter of triangular base = 10 + 8 + 6 = 24 mi.
L = height of the prism = 4 mi.
Plug the values into the formula
Surface area = 6*8 + (24)4
= 48 + 96
= 144 mi.²
Her brother is 7 years old at the moment. He will be 21 when his sister is 36.
Of course for a rectangle A = L × W and we need to be careful about the units.
Here that's
18900 sq cm = L × 180 cm
where the area's in sq cm so we converted the width. We get
L = 18900 / 180 = 105 cm
We're asked for the result in meters, so that's
Answer: 1.05 m
The perimeter of the outer rectangle is
18.4 m + 32.5 m + 18.4 m + 32.5 m = 101.8 m
Answer: 101.8 m
The area of the seating space is the big rectangle minus the small rectangle,
A = 18.4(32.5) - 15(28) = 178 sq m
Answer: 178 sq m
