What is the size of angle QRS

As reported by Cortez and Schlegel, the Dower‐related reconstruction typically yields a spatial QRS‐T angle from 66° to 81°, whereas those derived from Kors' regression‐related reconstructions have typically ranged from 44° to 65°, with values obtained from the true Frank leads being 35°–51°.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
