To calculate the area of triangle EAB. 1. Draw line EF parallel to line AB. 2. Join line EF to line AB at A and at B. 3. Count the number of squares in side rectangle ABHG and divide by 2 . Rectangle ABHG is a 6X11 grid. It has 66 squares in it. The area of EAB is 33 units2. G H E F B A
To calculate the area of triangle EAB. 1. Measure the base. 2. Measure the height. 3. Multiply the height by the base and divide it by 2. Base is 11units, height is 6 units11X6 = 66÷2 = 33 units². Remember to measure from the base line to the highest vertex E B A
