Answer:

Area of first shape = 97cm^2

Area of second shape = 506cm^2

Area of third shape =143 cm^2

First shape :

i. Area if rectangle in the fig. = l*b

= 12*4

= 48 cm^2

Now, in the same fig. we construct a line and make it a square,

ii. Area of square = s*s

= 7*7

= 49 cm^2

Area of whole shape = 48cm^2 + 49cm^2

= 97 cm^2

Second Shape :

i. Area of the rectangular shape(above one)

= l*b

= 29*14

= 406 cm^2

ii. Area of the rectangle (stick like shape)

= l*b

= 20*(29-24)

= 20*5

= 100 cm^2

Area of whole shape = (100 + 406) cm^2

= 506 cm^2

Third shape :

i. Area of the triangle = 1/2 *b* h

= 1/2 * 13 * 6

= 39 cm^2

ii. Area of the square = s*s

= 13*8

= 104 cm^2

Area of whole shape = (104 + 39) cm^2

= 143 cm^2

Hope it helps!

Use the explicit formula a↓n=a↓1+(n-1)d to find the 1000th term of the sequence below. 24,31,38,45,52,..

a(1000) = 24 + 999*7 = 7017 Thus your answer is A

the sum of 3 numbers is 9. tge second number is 3 less than the first.the thirf number is four morethan twice the first. find ea

<h3>The value of the first number, x, is eual to 2.</h3><h3>The value of the second number, y, is equal to -1.</h3><h3>The value of the third number, z, is equal to 8.</h3>

x + y + z = 9

y = x - 3

z = 2x + 4

Because we have values for y and z, we can find the exact value of x, which we can use to find the exact values for the other variables.

x + x - 3 + 2x + 4 = 9

Combine like terms.

4x + 1 = 9

Subtract 1 from both sides.

4x = 8

Divide both sides by 4.

x = 2

Now that we have a value for x, we can plug this value in to each other x value to solve for y and z.
