Lesson 4.0.3 Area missing parts

Find missing h

Area, A=bh

Find missing h

Area, A=bh/2 careful with the base...

Find missing h

Area A= (b1+b2)h/2

Find missing h

Area -= bh

Find missing h (you have an angle here..)

Area= bh you can move the 9 to the bottom (parallelograms..)

Find missing h (we have an angle here)

Area= bh/2

Find missing h

Area= bh

Find half of d1, then you can find d1 by doubling the answer! DONT DO THIS ONE

Area d1*d2 / 2 DON'T DO THIS ONE

Find the missing b

A=bh

the right triangle sides are 5 and 3 and h

A=(11+17)h/2

DON'T DO THIS ONEFind diagonal, after finding the side on the triangle, multiply by 2 and that is d1

DON'T DO THIS ONE

Area= d1 * d2 / 2

Find missing h (we have an angle here)

Area = bh/2

Base is 17 not 12.
