Answer:
884cm^2
Step-by-step explanation:
top triangle area=21*24/2=252
central triangle area=16*24/2=192
left n right triangle area (each)=22*20/2=220
total area of wood needed=252+192+220+220
=884cm^2
Total wood needed is the sum of the four triangles shown in the diagram.
The area can be calculated by using the triangle's area formula: 1/2xbasexheight
Total area=(1/2x24x21)+(1/2x24x16)+2x(1/2x20x22)
