What is the formula for the area of a triangle

• $A=bh$

• $A=lw$

• $A=s^2$

• $A=\frac{1}{2}bh$

What is the formula for the area of a parallelogram?

• $A=bh$

• $A=lw$

• $A=s^2$

• $A=\frac{1}{2}bh$

What is the formula for the area of a trapezium?

• $A=lw$

• $A=bh$

• $A=\frac{1}{2}\left(a+b\right)h$

• $A=\pi r^2$

Convert 10 meters to kilometers

• 10 m = 0.01 km

• 10 m = 10,000 km

• 10 m = 1 km

• 10 m = 0.1 km

The area of this trapezium is

• $\frac{20}{2}\times8=80\ units^2$

• $\frac{45}{2}\times8=180\ units^2$

• $20\times8=160\ units^2$

• $20+8+25+-9=62\ units$

Calculate the circumference of a circle with a diameter of 15 cm.

• $2\pi r=2\times\pi\times15=94.2cm$

• $\pi d=\pi\times15=47.1cm$

• $\pi\times152=706.9cm$

• $152=225cm$

What is the area of a circle with radius 4.2 cm?

• $\pi\times4.2^2=55.4cm^2$

• $\pi\times2.1^2=13.9cm^2$

• $2\times\pi\times4.2=26.4cm^2$

• $\pi\times4.2=13.2cm$
