Question

Given the figure as marked, find the perimeter and area.

Answer 1

Answer:

Step-by-step explanation:

Left triangle: it has two congruent legs because has an angle of 45 degrees

AB = $\sqrt{ 2 * 6^2} = 6\sqrt{2}$ cm

the triangle on the the right is half on an equilateral one

BC = 12 cm

CH = 6√3 cm

AC= (6 + 6√3) cm

2p = 6 + 6√3 + 12 + 6√2 = 18 + 6√3 + 6√2 = 6(3 + √3 + √2) cm

Area = [6(1+√3)  * 6]/2 = 18(1+√3) cm^2
