Answer:
Perimeter = 100mm
Area = 60mm
Step-by-step explanation:
P= (3x2) + (2x2) =10cm
10mm to 1cm
10cm x 10 = 100mm
A= b x h
= 3 x 2
=6cm
6x10=60mm
For the first question you just need to add up all the sides. so first add all the x numbers and then add all the plain numbers.
a perimeter is the total length around the shape.
X + 3x = 496
x = 496/4
X = 124
Another Number equal to 496-124 equal to 372
