Area of a Deltoid: Subtraction or addition to a larger shape

Calculation using percentages Verifying whether or not the formula is applicable Using Pythagoras' theorem Using external height Using ratios for calculation Identifying and defining elements Using variables Using additional geometric shapes Applying the formula Finding Area based off Perimeter and Vice Versa Calculate The Missing Side based on the formula

Question 1

Given the deltoid ABCD within the rectangle KMNG

Side AC=8 height DO of triangle ADC is equal to 3 cm

Calculate how much the area of the rectangle is equal to

Question 2

Given the deltoid ABFD and in its interior other 2 deltoids ABCD and CBFD

Given in cm AF=6 CF=2

Area of the deltoid CBAD=16

Calculate the area of the deltoid ABFD

Question 3

Given the deltoid ABCD inside the square ABKD

Given that the side AB is equal to the root 18

Diagonal AC=2

Calculate the deltoid DCBK
