What is the area of the composite figure
kati45 [8]

To solve this we will divide the given composite figure into three figures. The three figures will be 2 squares and 1 rectangle. Let's find their areas and add them!

\boxed{ \sf \: area \: of \: square =side ^{2}  }

  • Side 3 metre

\rm \implies \: area = 3 ^{2}

\rm \implies9

<em>Thus, The area of 1st square is 9m²...</em>

  • The area of second square will be also 9m², because the sides of both squares are equal.

<h3>Now area of the reactangle⤵️</h3>

  • Length = 6m
  • Breadth = 7+3=10m

\sf \: area \: of \: rectangle = length \times breadtg

\tt \dashrightarrow \: area = 10 \times 3

\tt \dashrightarrow \: area = 30m ^{2}

<em>Thus, The area of rectangle is 30m²....</em>

  • Now, Add area of all the figures to get the total area.

\bf \:total \: area = 9 + 9 + 30 \\   \bf= 48m {}^{2}

<h3><em>Therefore, The total area of the composite figure is 48m²...~</em></h3>

The area of a triangle is 80in^2. The ratio of the length of its base to its height is 5:2. What are the base and height of the
Anuta_ua [19.1K]

Answer: base = 20 inches , height = 8 inches

Step-by-step explanation:

The formula fro calculating the area of  a triangle , given the base and the height is given as ;

A = \frac{1}{2}bh

The ratio of its base to the height is given as 5: 2 , this means that

2b = 5h , that is

b = \frac{5h}{2}

Substitute this into the formula for finding area , that is

80 = \frac{1}{2} X \frac{5h}{2} X h

80 = \frac{5h^{2}}{4}

Therefore :

5h^{2} = 80 x 4

5h^{2} = 320

h^{2} = 320 / 5

5h^{2} = 64

h = 8 inches

Substitute h = 8 into b = \frac{5h}{2} , then

b = 20 inches

Therefore , the base of the triangle is 20 inches and the height is 8 inches
