4 x 12 is 48 and then plus 20 is 68
ANswer to 1 is 68.

A boy stands 1 meter away from a lamppost. He is 1.8 meters tall and casts a shadow 2 meters long in the light from the lamp
The diagram is attached below using the given information
We have two similar triangle
Triangle ACD is similar to triangle ABE. So the sides are in proportional

AC = AB + BC = 3m

2x = 1.8 * 3 (cross multiply)
2x = 5.4
Divide by 2 on both sides
x = 2.7
Height of Lamppost is 2.7 meter
Answer:
203
Step-by-step explanation:
When calculating surface area, you add the area of each side.
Base: LxW = 7x7 = 49
Triangle Sides: 1/2 b x h = 1/2(7) x 11 = 38.5
4 sides: 38.5x4 = 154
154+49 = 203
