Rectangles and Parallelograms (10.1/10.2)
10.1 AREA AND PERIMETER OF RECTANGLESEssential Question: How do you find the
area of a rectangle?
Base x Height (b x h)2b + 2h
Side x Side (s2)4s
A =s2 = 52=25in2
C= 4s= 4(5)=20in
A= b x h= 9 x 4= 36cm2 C= 2b + 2h= 2(9) + 2(4)=26cm
13m
12m
A= b x h= 13 x 12= 156m2
C= 2b + 2h= 2(13) + 2(12)=50m

10.2 AREA OF PARALLELOGRAMSEssential Question: How do you use area
of a parallelogram to find the height?
Quadrilateral w/ 2 pairs of || sides
b x h
A= b x h=15 x 8=120in2
A= b x h56= 4 x h56/4=h14units=h
A= b x h60= b x 1260/12=55m=b
