What is the area of the composite shape?( 20 points )

Area of the shape =61 ft^2

Step-by-step explanation:

Firstly,

Area of the Rectangle = l*b

= 4*10

= 40 ft^2

Now, Area of the triangle

We have, base = 6 and height = 3+4 = 7

= 1/2*b*h

= 1/2 * 6 * 7

=21 ft^2

Area of the fig. = (40 + 21 )ft^2

= 61ft^2

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

d. vertex
