Answer:
perimeter-
perimeter outer rectangle = 2 (l+b)
=2×8+9
= 2×17
2×17 =34 cm sq.
perimeter of inner rectangle = 2 (l+b)
= 2×5+3
=2× 8
= 16 cm sq.
perimeter of shaded portion= 34 - 16
= 18 cm sq.
area-
<em>area</em><em> </em><em>of</em><em> </em><em> </em><em>inner</em><em> </em> rectangle =l×b
l×b = 3×5
3×5=15
15 cm sq.
area of outer rectangle =l×b
l×b= 9×8
9×8= 72
72 cm sq.
area of shaded portion = 72 -15 =57 cm sq.
hey there! In second method i have done first area of inner rectangle but you have to do first area of outer rectangle...
hope it helps you....
Answer:
h = 80
Step-by-step explanation:
Remark
The general Volume formula for a pyramid is V = 1/3 * B * h
Givens
base edge = 3 m
V = 240 m^2
Solution
V = 1/3 * B * h
B = s^2
B = base edge^2
B = 3^2
B = 9
240 = 1/3 * 9 * h multiply by 3
240 * 3 = 9 h Divide by 9
80 = h
