Answer 1

Answer:

Rectangle,

• area= length * breadth
• perimeter=2(length+breadth)

square,

• area=side*side
• perimeter=4*side

Triangle,

• area=1/2* base*height
• area by heron's formula
• =√s*(s-a)(s-b)( s- c) where s is semi perimeter and a,b and c are sides of triangle.
• perimeter=a+b+c.

cube,( measure of side=a unit)

• lateral surface area=4a^2
• total surface area =6a^2
• diagonal √3 a unit

cubiod,

• lateral surface area= 2h( l+ b)
• total surface area=2( lb + bh+ lh)
• diagonal=√l^2+b^2+h^2
