Answer:
132cm^2
Step-by-step explanation:
first break the shape up into component shapes. the shape is made of two rectangles and two triangles. the area for a rectangle is A=BH where b is base and h is height. the area of a right triangle is BH/2 where b is the base and h is the height. you are given the base and height of the top rectangle 4x7. To find the area of the triangles and the second rectangle you have to do some algebra. the total base length is 19cm and the top rectangle has a length of 7cm so 19-7 leaves you with 12cm to spare and there is two symmetric triangles on each side so 12/2 is 6. now we know all the measurements and can solve.
If the two triangles are congruent, you can just look at both triangles and see what is missing from each. They are all the same! :D
z = 10 yd
v = 7.9 yd
y = 38°
u = 6.2 yd
x = 90°
And to find w...
You know that the sum of all angles in every triangle is 180°. We know that two angles are 38° and 90°. Add them and subtract it from 180° to find the remaining angle.
90 + 38 = 128
180 - 128 = 52
So w = 52°
Hope this helps! :D
