Answer:
45750 cm²
Step-by-step explanation:
<h3>Area of triangle:</h3>
a = 4 and c = 5
base length = 3ac²
= 3 * 4 * 5 * 5
= 300 cm
height = 5 cm more than the base length
= 300 + 5
= 305 cm
Answer:
I am a person and I'm going to say it is. c.
Answer:
Given that the scale on map is 1 cm:5 km. hence, the distance of the map corresponding to the actual distance of 14 km.
Step-by-step explanation:
Answer:
40units²
Step-by-step explanation:
find the shapes you know the formula of. There's two shapes a rectangle and a trapezoid.
do the formula for rectangle
A = bh
A = 8×2
A = 16
Now the formula for Trapezoid
A = 1/2h(b+b)
A = 1/2×4(4+8)
A = 1/2×4(12)
A = 1/2(48)
A = 24
16+24 = 40
The figure consists of a rectangle and a circle.
first lets find the sides of the triangle
sides of the triangle are 4+4=8 and 3+1=4
therefore area of the rectangle is 8*4=32
now area of semicircle =πr^2/2 = π2^2/2=2π=6.3
we have to add the area of rectangle with the area of semicircle
this is because it the given figure no part of area of circle and rectangle are in common.
therefore total area of given figure = 32+6.3=38.3
