1. A rectangle, with a length of 8cm and width of 10cm.


2. A triangle, with a height of 4cm and a base of 8.5cm.

Answer 1

1. formula- a=lh answer: 8•10=80
l=length h=height

2. formula- a=bh1/2 or a=bh/2 answer: 4•8.5/2= 17
b=base h=height

Answer 2

1. A=80. wl=a that is the same as 10x8=80

2.A=17. 4·8.52=17
