Answer:
Step-by-step explanation:
Area equation of the parallelogram
- A = bh, where b- base, h - height
Looking at the picture, we can see the right triangle is isosceles as one of interior angles is 45°. It has hypotenuse of 7 and legs of h.
As per property of 45° right triangle the hypotenuse is √2 times the leg.
It gives us
- h√2 = 7 ⇒ h = 7/√2 = 4.95 (rounded)
Now find the area
