196ft^2

Step-by-step explanation:

direct the diagram as shown in my image attachment

A = 1/2 x (18-(9-7)) x (6+8) = 112ft^2

B = 2 x (6+8) = 28ft^2

C = 7 x 8 = 56ft^2

total area = 112 + 28 + 56 = 196ft^2

196 ft²

Explanation:

Consider the given image.

Area of ΔABC

= ½bh

= ½ × (18 ft + 7 ft - 9 ft) × (8 ft + 6 ft)

= ½ × 16 ft × 14 ft

= 8 ft × 14 ft

= 112 ft²

Area of rectangle BEDC

= lw

= (8 ft + 6 ft) × (9 ft - 7ft)

= 14 ft × 2 ft

= 28 ft²

Area of rectangle EFGH

= lw

= 8 ft × 7 ft

= 56 ft²

Total area of the figure

= Area of ΔABC + Area of rectangle BEDC + Area of rectangle EFGH

= 112 ft² + 28 ft² + 56 ft²

= 196 ft²

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
