Answer:

b= 26

Step-by-step explanation:

there are 2 triangles

area of the right angles triangle

1/2bh= 1/2 x3 x4 = 6cm²

for the next triangle we use pythagoras theorem to calculate the height

3²+4² = h² = 9+16 = 25

h = √25 =5

1/2bh = 1/2 x 5 x8 = 20

adding the two areas will give the area of the figure = 20 + 6 = 26
