Answer:
336 cm²
Step-by-step explanation:
1 rectangle 24 cm by 12 cm
1 triangle with base 12 cm and height 8 cm (combining the two small triangles into 1 larger triangle)
SA = 24 cm * 12 cm + 12 cm * 8 cm / 2
SA = 288 cm² + 48 cm²
SA = 336 cm²
Answer:
Base of the ladder is 3 meters away from the building.
Step-by-step explanation:
Let's use Pythagoras theorem to solve.
Pythagoras theorem says,

Here let horizontal distance is "a''
Vertical distance of window is 4 m
So, b=4
The Rafi leans 5 m ladder against the wall. So, c=5.

Simplify it

Subtract both sides 16

Take square root on both sides
a=±3
So, base of the ladder is 3 meters away from the building.

Answer:
5.89 feets
Step-by-step explanation:
Arc length :
L = θ/ 360° * 2πr
Diameter = 15 ; Radius, r = 15 / 2 = 7.5
θ = 45°
L = (45/360) * 2*3.14 * 7.5
L = 0.125 * 2 * 3.14 * 7.5
L = 5.89 feets
