Question

Please help me with this.

Answer 1

Area of 2 rectangles :30✖️10✖️2=600
Area of 1 rectangle: 16✖️30=480
Height of triangle: make a vertical line at the middle of 16cm. Is 8cm
Through the Pythagorean theorem, the height is 6cm.
So the area of 2 triangles:16✖️6=96
Add all areas together:96+480+600=1176
1176 is the tile needed to take cover.
