Answer:
5.8
Step-by-step explanation:
Let's use the area formula,
our base is 4.6cm, so b=4.6
our height is 2.5cm, so h=2.5
plug this in for our <em>b </em>and <em>h</em>
<em /><em>, </em>multiply the 4.6 by the 2.5 and you get 11.5
a=1/2*11.5, multiply and we get
a= 5.75, rounding our answer to 1 decimal would give us,
a=5.8
