sp2606 [1]

Answer:

1.) The answer is b = 6

2.) The answer is t = 10

Step-by-step explanation:

For the first equation in order to fin out the answer we do.....

b + 8 = 14

b + 8 - 8 = 14 - 8

b = 6

For the second question we do....

25 - t = 15

25 - t + t = 15 + t

25 = 15 + t

25 - 15 = 15 + t -15

Answer:

The answer is 2240m².

Step-by-step explanation:

Given that the formula of area of trapezium is A = 1/2×(a+b)×h where a and b represents the length and h is height :

$area = \frac{1}{2} \times (a + b) \times h$

$let \: a = 50 \\ let \: b = 90 \\ let \: h = 32$

$area = \frac{1}{2} \times (50 + 90) \times 32$

$area = \frac{1}{2} \times 140 \times 32$

$area = 70 \times 32$

$area = 2240 \: {m}^{2}$
