Find the area of the quadrilateral in the figure. a. 13.64 b. 22.25 c. 19.64 d. 15.25

The answer is option C.

This is a composite figure made up from a right angled triangles ( with sides 3, 4 and 5) and an isoceles triangle with 2 sides both equal to 6.

Area of the right angled triangle =    1/2 * 3 * 4 = 6 sq units.

Height of the isosceles triangle = sqrt (6^2 - 2.5^2) =   5.454

Its area = 1/2 * 5 * 5.454 = 13.635

So area of the whole figure = 19.64 sq units

ok

step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
