Find the area enclosed
Answers
Step-by-step explanation:
ABCD is a square
area if square= side × side
=4×4
=16cm²
ABC is a triangle
area of triangle= 1/2×base×height
base = 4 cm. height=6-4=2cm
area= 1/2×4×2
=4cm²
total area= 16+4=20cm²
Step-by-step explanation:
Area of square=4×side
=4×4cm²
=16cm²
Length of AC=Length of DE=4cm (all sides of square are equal)
Construction=Let point intersecting AC be F
Total length=6cm
CD=4cm
BF=6cm-4cm
=2cm
Area of triangle ABC=1/2×base×height
=1/2×AC×BF
=1/2×4×2
=4cm²
Area of enclosed figure=Area of square+Area of triangle-AC (AC is common)
=16cm²+4cm²-4cm
=16cm²
