Answer:
0.324m^2 ; 18 ft
Step-by-step explanation:
Given the triangle :
Base (b) of triangle = 54cm
Height (h) of triangle = 1.2m
Area(A) of a triangle is given by:
0.5 * base * height
Base = 54cm = 54/100 = 0.54 m
Therefore,
A = 0.5 * 0.54m * 1.2m
A = 0.324m^2
2.) Average of the two bases in the trapezoid :
From the trapezium Given :
Base 1 = 15 feets
Base 2 = 7 yards
1 yard = 3 Feets
Therefore, base 2 in Feets = 7 * 3 = 21 Feets
Average of the two bases :
(21 Feets + 15 Feets) / 2
= 36 Feets / 2
= 18 Feets
360/9= 40
180-40= 140
140/2= 70
X=70
