Answer:

11/84

Step-by-step explanation:

Simplify 7/8 +2/3 to 37/24

4/7 × 37/24 -3/4

Use this rule: a/b x c/d = ac/bd

4 x 37 - 3

7 x 24 - 4

Simplify 4 ×37 to 148

148/7 x24 - 3/4

Simplify 7 ×24 to 168

148/168 - 3/4

Simplify 148/ 168 to 37/42

37/42 - 3/4

Simplify.

anddd the answer is

11/84

Answer:

$\boxed{\bold{\huge{\boxed{Area\ of\ Trapezium = 150\ cm\²}}}}$

Step-by-step explanation:

Using Pythagorean Theorem first to find EC

$\sf CB^2 = EB^2+EC^2\\Where \ CB = 13 \ and \ EB = 5 \\13^2 = 5^2 + EC^2 \\169 - 25 = EC^2 \\EC^2 = 144\\Taking \ sqrt \ on \ both \ sides\\EC = 12 \ cm$

Given that:

AE = EC

AE = 12 cm

Now,

AB = AE + EB

AB = 12 + 5

AB = 17 cm

ABCD is a trapezoid / trapezium

So,

Area of Trapezium = $\sf \frac{AB+DC}{2} (EC)$

Where AB = 17 , DC = 8 and EC = 12

Area of Trapezium = $\sf \frac{17+8}{2} ( 12)$

Area of Trapezium = (25)(6)

Area of Trapezium = 150 cm²
