Calculate Deltoid Area: Using 12cm and 16cm Diagonals

Question

ABDC is a deltoid.

AB = BD

DC = CA

AD = 12 cm

CB = 16 cm

Calculate the area of the deltoid.

00:00 Calculate the kite's area

00:03 Let's use the formula for calculating a kite's area

00:12 (diagonal multiplied by diagonal) divided by 2

00:18 Let's substitute appropriate values and solve to find the area

00:34 And this is the solution to the question

First, let's recall the formula for the area of a rhombus:

(Diagonal 1 * Diagonal 2) divided by 2

Now we will substitute the known data into the formula, giving us the answer:

(12*16)/2
192/2=
96

96 cm²
