A rectangle has a perimeter of 30 cm. If the length is twice the width, what is the area of the rectangle?
50cm squared
Length = 10cm
Width = 5cm
10 x 5 = 50
A composite shape consists of a rectangle (length = 8 cm, width = 3 cm) and a right angle triangle (side 1= 3 cm, side 2= 4 cm, side 3 = 5cm ). What is the total perimeter if the 5cm triangle side is attached to one of the shorter sides of the rectangle?
Rectangle perimeter: 2(8+3)=22 cm
Triangle sides 3+4+5=12 cm
Total perimeter:22 + (12-5)
= 22 +7
= 29cm

=12×40000
=480000cm2
=48m2
