Find the area of the irregular figure. Round to the nearest hundredth.
blondinia [14]

Answer:

137.5 in^2

Step-by-step explanation:

So, this is basically a rectangle and two right-sides triangles.

First the rectangle: Formula is A=wl

Replace the Values: A = 14*7 98 in^2

Then we solve for the two right-sides triangles.

A= 1 /2a h= 1 /4 b ^2 sin (2 θ )

Top trinangle= A = 25.5 in^2     (height 7 in base 7 in)

Bottom Trinagle  A = 14 in^2      (height 7 in base 4 in)

Add results:

98+25.5+14 = 137.5 in^2

Which pairs of polygons are congruent?
svetlana [45]

The <em><u>correct answer</u></em> is:

pairs 1 and 3

Explanation:

Congruent figures are the same size and the same shape.

Pair 1 has two polygons that are the same size and same shape; they are congruent.

Pair 2 has two polygons that are not the same size; the "stick" of the t shape of one figure is longer than the "stick" of the second figure.

Pair 3 has two polygons that are the same size and same shape; they are congruent.

Pair 4 has two polygons that are the same shape, but the first figure in green is larger than the second shape in red; this means they are not congruent.
