Step-by-step explanation:
area of missed triangle =1/2×2×4=4 cm2
area of whole rectangle =4×8=32 cm2
area of shape =32_4 =28cm2
The first picture shows you how to solve it and the second picture is showing you how to get your answer in simplest form.
24. 8x3=24
12x2=24
It would be 6/24 (3/12) and 9/24 (3/8)
