Question

Find the area of the figure. PLEASE HELP I NEED IT URGENT PLEASE

Answer 1

Answer:

5. 45.5

8. 75

Step-by-step explanation:

5. Area of larger right triangle: AB/2

Given A = 7, B = 18

A = 7(18)/2 = 63

Area of smaller right triangle: AB/2

Given A = 7, B = 18 - 13 = 5

A = 7(5)/2 = 17.5

So the area of the shaded triangle is 63 - 17.5 = 45.5

8. Area = area of triangle + area of rectangle

Triangle: A = HB/2 = (3 x 10)/2 = 15

Rectangle: A = lw = 10 x 6 = 60

15 + 60 = 75

Hope this help

Answer 2

Answer:

#5

Area = Area of bigger triangle - Area of small triangle

${ \rm{area = ( \frac{1}{2} \times b_{b} \times h_{b}) - ( \frac{1}{2} \times b_{s} \times h _{s} )}} \\ \\ { \tt{area = ( \frac{1}{2} \times 18 \times 7) - ( \frac{1}{2} \times (18 - 13) \times 7) }} \\ \\ { \tt{area = (9 \times 7) - (2.5 \times 7)}} \\ \\ { \underline{ \tt{ \: \: area = 45.5 \: \: sq \: units \: \: }}}$

#8

Area = area of square + area of two right angled triangles

${ \tt{area = (s \times s) + 2( \frac{1}{2} \times b \times h)}} \\ \\ { \tt{area = (6 \times 10) + (3 \times 5)}} \\ \\ { \underline{ \tt{ \: \: area = 75 \: \: {m}^{2} \: \: }}}$
