are can split the shape up
see attachment
the area of the bottom rectangle is length times width=10 times 20=200 cm²
the area of the higher rectangle
hmm, te width willl be 20-5-5=10
the height is 7cm
so the area is 7 times 10 or 70cm²
the area of the triangle is 1/2 times base times height
the base is 10
the height is 22-10-7=5
the are=1/2 times 10 times 5=5 times 5=25 cm²
in total it is 200+70+25=295cm²
the are is 295cm²
